Neurons in the caudal portions of the medial and descending vestibular nuclei and in vestibular cell group f that project to the cervical or lumbar spinal cord were located by antidromic spinal stimulation. These caudal vestibulospinal tract (CVST) neurons have a median conduction velocity of 12 m/sec, which is well below the conduction velocities of typical lateral or medial vestibulospinal tract (LVST, MVST) axons. The descending fiber trajectories of CVST neurons, determined by comparing thresholds for activation of each neuron from six points in the spinal white matter, were remarkably diverse. Unlike LVST and MVST axons, which are located in the ipsilateral ventral funiculi, CVST axons can be found in both the ventral and dorsolateral funiculi on both sides of the spinal cord. The CVST system is thus both anatomically and physiologically different from the LVST and MVST.
通过逆向脊髓刺激定位了内侧和下行前庭核尾端部分以及前庭细胞群f中投射至颈髓或腰髓的神经元。这些尾侧前庭脊髓束（CVST）神经元的平均传导速度为12米/秒，远低于典型的外侧或内侧前庭脊髓束（LVST、MVST）轴突的传导速度。通过比较脊髓白质中六个点对每个神经元的激活阈值来确定CVST神经元的下行纤维轨迹，结果显示其差异显著。与位于同侧腹侧索的LVST和MVST轴突不同，CVST轴突可在脊髓两侧的腹侧索和背外侧索中找到。因此，CVST系统在解剖学和生理学上均与LVST和MVST不同。
